DETAILED DESCRIPTION

The embodiments containing the technical solutions of the presentdisclosure are described in detail with reference to the accompanyingdrawings. The embodiments hereinafter are only used to clearly describethe technical solutions of the present disclosure. Therefore, theseembodiments are only used as examples, but are not intended to limit theprotection scope of the present disclosure.

In one aspect of the embodiments of the present disclosure, a mesh frameand a chair are provided, to simplify a structure of the mesh frame andmounting of the mesh, improve production and assembling efficiencies,and beautify the chair.

Referring to FIG. 1 to FIG. 3, an overall structure and a sectionalstructure of a mesh frame, and a sectional structure of a recessaccording to some embodiments of the present disclosure areschematically illustrated.

As illustrated in the drawings, a mesh frame 100 includes a side frame110. The side frame 110 includes a first face 111 that is in contactwith a human body during use. The first surface 111 is provided with arecess 120. The recess 120 obliquely extends towards an inner side ofthe side frame 110, and is configured to snap a mesh to the mesh frame100.

Specifically, a distance from an opening 121 of the recess 120 to anouter edge of the mesh frame 100 is l₁, and a distance from a bottomwall 122 of the recess 120 to the outer edge of the mesh frame 100 isl₂, wherein l₁<l₂, such that the recess 120 is obliquely arranged. InFIG. 2, an x direction is a direction horizontally pointing from anouter side of the mesh frame 100 to an interior, a y direction is adepthwise direction pointing from the bottom wall 122 of the recess 120to the opening 121, and the x direction and the y direction define anangle within a range of 90°<α<180°.

By the obliquely arranged recess 120, the mesh, when being mounted onthe side frame 110 of the mesh frame 100, may be sleeved onto the recess120. In addition, by obliquely arranging the recess 120, the outer edgeof the mesh may be effectively snap-fitted into the recess 120, whichfacilitates stably and securely sleeving of the mesh onto the mesh frame100. Furthermore, the mesh frame 100 has a simple structure, andmounting of the mesh is convenient and quick, which may address theproblem that a snap strip needs to be arranged to tightly press the meshor a two-layer structure needs to be arranged to tightly press the mesh,and may effectively improve production and assembling efficiencies.Meanwhile, the recess 120 is arranged on the first face 111 of the meshframe 100 that is in contact with the human body during use, such thatthe outer edge of the mesh frame 100 has a complete and smooth surface,and a beautiful structure.

Still referring to FIG. 1, in a specific embodiment as illustrated inFIG. 1, the recess 120 may be arranged to be annular, and surround anedge of the first face 111 of the mesh frame by one turn, such that theentire edge of the mesh may be snap-fitted into the recess 120.

A person skilled in the art shall understand that the illustrations inthe drawings are merely examples, and in other embodiments, two recesses120 may also be symmetrically arranged, which are respectively arrangedon two opposite edges of the first face 111 of the mesh frame. Byreceiving and snap-fitting of the two sides of the mesh, the mesh isfixed to the mesh frame 100.

Still referring to FIG. 3, in some embodiments, a minimum distance libetween the opening of the recess 120 and the outer edge of the sideframe 110 may be greater than 2 mm. In the case that li is greater than2 mm, in one aspect, the surface of the outer edge of the mesh frame 100is flat from an outer view angle, and in another aspect, a wallstructure between an inner wall of the recess 120 and the outer edge ofthe mesh frame 100 has a specific strength, and is not easily broken.

Still referring to FIG. 3, in some embodiments, inner walls of two sidesof the recess 120 are parallel to each other. Such configurationsfacilitate machining, and may provide a sufficient space forsnap-fitting the mesh. The inner walls of the two sides of the recess120 are arranged to face each other.

Still referring to FIG. 3, in some embodiments, a width w between theinner walls of the two sides of the recess 120 ranges from 2 to 5 mm.

When the width w between the inner walls of the two sides of the recess120 is too small, the edge of the mesh fails to be snap-fitted. When thewidth w between the inner walls of the two sides of the recess 120 istoo large, the mesh may be easily released from the recess. Therefore,the width w between the inner walls of the two sides of the recess 120is defined to be within the range of 2 to 5 mm to ensure that the edgeof the mesh is smoothly snap-fitted and is not easily released from therecess.

Still referring to FIG. 3, in some embodiments, a height h between theinner walls of the two sides of the recess 120 ranges from 5 to 20 mm.

When heights h of the inner walls of the two sides of the recess 120 aretoo small, the mesh fails to be securely connected. When the heights hare too large, a thickness of the structure of the mesh frame 100 may beincreased, and machining may be difficult and production cost may beincreased. Therefore, the heights h of the inner walls of the two sidesof the recess 120 is defined to be within the range of 5 to 20 mm, suchthat the mesh is stably and securely connected, and the machining isconvenient.

It should be noted that when the heights of the inner walls of the twosides of the recess 120 are inconsistent, the heights both need to beensured to be within the range of 5 to 20 mm. The height of the innerwall, proximal to the outer edge of the mesh frame 100, of the recess120 is defined in order to ensure a clean and attractive surface of theouter structure of the mesh frame 100. The height of the inner wall,proximal to the interior of the mesh frame 100, of the recess 120 isdefined in order to ensure that the mesh is effectively snap-fitted intothe recess 120.

Referring to FIG. 1 and FIG. 4 to FIG. 6, structures of a cushion meshframe, a backrest mesh frame 200, a lumbar support mesh frame 300, and aheadrest mesh frame 400 according to some embodiments of the presentdisclosure are respectively illustrated. In some embodiments, the meshframe 100 may include at least one or more of the cushion mesh frame,the backrest mesh frame 200, the lumbar support mesh frame 300, and theheadrest mesh frame 400.

It should be noted that description and illustration hereinafter of theembodiments of the mesh frame 100 are all given using the cushion meshframe as an example. However, the practice is not limited to the cushionmesh frame, and the same applies to the backrest mesh frame 200, thelumbar support mesh frame 300, and the headrest mesh frame 400.

Still referring to FIG. 3, in some embodiments, the opening of therecess 120 is provided with an arc chamfer.

When the mesh is sleeved onto the mesh frame 100, configuration of thearc chamfer may effectively prevent the chamfer or edge from scratchingthe mesh and thus causing unnecessary loss, and ensure that thestructure is stable and reliable when the mesh is sleeved onto the meshframe 100.

Still referring to FIG. 3, a perspective view of the mesh frame 100according to the embodiments of the present disclosure is illustrated.In some embodiments, a minimum distance l₃ between the inner wall of therecess 120 and an inner edge of the side frame 110 may be greater than 2mm.

l₃ is defined to be greater than 2 mm in order to ensure a specific wallthickness of the side frame 110 at the recess 120, and to prevent theside frame 110 from being bent and broken due to smaller wall thickness,and hence prevent the structure of the mesh frame 100 from damage.

According to another aspect of the embodiments of the presentdisclosure, a chair is provided, which is capable of reducing steps ofmounting the mesh, improving stability in fixing the mesh, andsimplifying the structure of the mesh frame. In this way, productioncost of the chair is lowered, and assembling efficiency of the chair isimproved.

Referring to FIG. 7, a schematic exploded structure of a mesh in a chairaccording to an embodiment of the present disclosure is illustrated. Achair 10 includes a mesh frame. The mesh frame may be the mesh frame 100as described in the above embodiment.

Still referring to FIG. 7, in some embodiments, a side frame of the meshframe is provided with a mesh 600. An outer edge of the mesh 600 issnap-fitted into a recess of the mesh frame.

In a specific embodiment as illustrated in FIG. 7, the mesh frameincludes a cushion mesh frame 500, a backrest mesh frame 200, a lumbarsupport mesh frame 300, and a headrest mesh frame 400.

A person skilled in the art shall understand that the illustrations inthe drawings are only examples. In other embodiments, the mesh frame mayinclude at least one or more of the cushion mesh frame 500, the backrestmesh frame 200, the lumbar support mesh frame 300, and the headrest meshframe 400.

In some embodiments, a thickness of an outer edge of the mesh 600 may begreater than a minimum width of the recess.

The thickness of the outer edge of the mesh 600 is defined to be greaterthan the minimum width of the recess, such that when the mesh 600 issnap-fitted into the recess, the recess applies a specific clippingforce to the mesh 600. In this way, the mesh 600 is prevented fromreleasing when a human body is seated on the mesh 600 or leans againstthe mesh 600.

In some embodiments, the outer edge of the mesh 600 is elastic.

The outer edge of the mesh 600 is defined to be elastic, such that whenthe outer edge of the mesh 600 is snap-fitted into the recess, aspecific force is applied to an inner wall of the recess facing towardsthe interior of the mesh frame. In this way, the mesh 600 is reliablyand securely snap-fitted onto the mesh frame.

Referring to FIG. 8, in some embodiments, the chair may include a snapstrip 700.

The snap strip 700 is snapped into the recess. The outer edge of themesh 600 is clamped between the snap strip and the recess.

Configuring the mesh 600 and the snap strip 700 as separate structuresfacilitates disassembling and replacement of the mesh 600.

Referring to FIG. 9 to FIG. 11, in some other embodiments, the outeredge of the mesh 600 may be fixed with the snap strip 700, and the snapstrip 700 is snapped into the recess.

In practice, the snap strip 700 may be fixed to the outer edge of themesh 600 by bonding or sewing.

The snap strip 700 is fixed to the outer edge of the mesh 600 to form anintegral structure with the mesh 600. In this way, the number of partsmay be reduced, and hence mounting and fixing of the mesh 600 on themesh frame may be facilitated.

In the chair 10 according to the embodiments of the present disclosure,configuration of the mesh frame achieves quick and convenient mountingof the mesh 600.

Specifically, by configuring the recess on the first face 111 in contactwith the human body during use of the mesh frame, the mesh 600 isprevented from being sleeved onto the outer edge of the mesh frame, suchthat the entire structure is less attractive, and wear may be easilycaused to the mesh 600. In addition, no fixing frame needs to be coveredon the mesh 600 to fix and protect the mesh. This simplifies thestructure for fixing the mesh, reduces the production cost, andeffectively improves the efficiency of mounting the mesh 600. Uponassembling of the mesh 600 on the mesh frame of the chair 10, from theperspective of a side, the edge of the mesh frame on the outer side ofthe recess is presented. Therefore, during manufacture and design, abetter visual effect and a quality sensation of the chair 10 may beachieved by changing colors and shapes and structures of the outer edgeof the mesh frame.
